Description

Technical Field

[0001] The utility model relates to a sewage treatment device, in particular to a spliced and assembled buried sewage treatment device. Background Art

[0002] At present, the buried sewage treatment device has abandoned the traditional brick masonry construction method, but is composed of multiple sewage tanks manufactured by rotational molding technology through splicing and assembly. This kind of rotational molding sewage tank has the advantages of light weight, convenient manufacturing and flexible on-site splicing and assembly, so it is widely used; however, the traditional rotational molding sewage tanks are all vertical rectangular tanks, and are assembled in sequence along the longitudinal or transverse direction. For the sewage treatment device assembled in this way, the sewage tank at the outermost edge is prone to tipping outwards during use because it is only tightly constrained on one side, and the structural stability is poor. Therefore, usually a frame is needed to restrain these spliced and assembled sewage tanks to maintain the integrity. However, it is very troublesome in actual use because it is rather troublesome to disassemble and assemble the frame during the assembly process of multiple sewage tanks, and the size of the frame has also restricted the splicing and assembly methods and the number of spliced and assembled sewage tanks of multiple sewage tanks, resulting in poor application flexibility during the splicing and assembly of multiple sewage tanks; at the same time, there is always a height difference in the construction site, so that this kind of framed sewage treatment device can only be applied to the ground. When buried, the adjacent two sewage tanks are mainly spliced and assembled through joint sockets or connected by pipelines. However, both of these two structural methods cannot be adjusted in height after the splicing and assembly are completed. Therefore, it cannot be used normally under this special buried condition, and it is also easy to crush the connection between the two during the backfilling of earthwork, thereby causing damage and leakage at the splicing point. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a spliced and assembled buried sewage treatment device with good structural stability after splicing and assembly, flexible splicing and assembly methods, simpler use, which can also adaptively adjust the splicing height between adjacent two tanks according to the height difference existing in the construction site, and effectively avoid the backfilled earthwork from crushing the splicing point.

[0004] The technical problem of the utility model is realized through the following technical solutions:

[0005] A spliced and assembled buried sewage treatment device includes two bent tanks and several straight tanks. The two bent tanks are respectively arranged at both ends with their bent openings facing each other. The two bent tanks are directly spliced and assembled end to end to form a circular sewage treatment device, or several straight tanks are jointly spliced and assembled between the two bent tanks to also form a circular sewage treatment device end to end.

[0006] The end faces of the two curved tanks are in contact with each other and are assembled in a detachable splicing manner; the end face of each curved tank is in contact with the end face of the adjacent straight tank and is assembled in a detachable splicing manner; the end faces of every two adjacent straight tanks are in contact with each other and are assembled in a detachable splicing manner.

[0007] Between the end faces of the two curved tanks, between the end face of each curved tank and the end face of the adjacent straight tank, and between the end faces of every two adjacent straight tanks, there are respectively provided with concave-convex dovetail structures that constitute detachable splicing assemblies.

[0008] The concave-convex dovetail structure is a splicing assembly structure that is disassembled and assembled in the up-down direction.

[0009] The described sewage treatment device is in a circular shape, or an elliptical shape, or a long straight circular shape, or a rectangular shape.

[0010] At the bending part of each curved tank, there are provided a top reserved platform and a pipe orifice reserved platform.

[0011] On each of the straight tanks, there are provided a top reserved platform and a side reserved platform arranged on the side of the top reserved platform.

[0012] On the outer surface of each curved tank, there are provided multiple solid ring ribs that radially surround and multiple solid arc ribs that are distributed in a concentric circle diffusion shape from the inner side of the bend. Each solid ring rib is cross-connected with each solid arc rib to form a whole.

[0013] The multiple solid ring ribs and the multiple solid arc ribs are arranged in a fan-shaped strengthening area on the outer surface of each curved tank, and there is a blank area reserved between the fan-shaped strengthening area and the concave-convex dovetail structures at both ends of each curved tank.

[0014] On the outer surface of each straight tank, there are provided multiple solid ring ribs that radially surround and multiple solid transverse ribs that extend along the axial direction. Each solid ring rib is cross-connected with each solid transverse rib to form a whole.

[0015] Compared with the prior art, the utility model mainly constitutes a sewage treatment device by using two curved tanks and several straight tanks, and arranges the two curved tanks at both ends in a way that the curved openings face each other. Then, according to the actual situation of the construction site, the two curved tanks are directly spliced and assembled end to end to form a circular sewage treatment device. It is also possible to splice and assemble the two curved tanks through several straight tanks and connect them end to end to form a circular sewage treatment device. Obviously, through this splicing and assembling structure, not only the splicing and assembling method is more flexible, but also the formed sewage treatment device forms a circular shape with the head and tail connected. Therefore, without the need for additional frameworks to bind, the overall structure can always maintain stability, and the use is also simpler. At the same time, between the end faces of the two curved tanks, between the end face of each curved tank and the end face of the adjacent straight tank, and between the end faces of every two adjacent straight tanks, there are respectively provided concave-convex dovetail structures to form a detachable splicing and assembling structure. In particular, the concave-convex dovetail structure is a splicing and assembling structure that can be disassembled and assembled in the vertical direction. By adopting this detachable splicing and assembling structure, the sewage treatment device can not only adaptively adjust the splicing height between adjacent tanks according to the height difference of the terrain at the construction site, making it convenient to be used normally under such special buried conditions, but also effectively avoid the backfilled soil from crushing the splicing part, thereby eliminating the risk of damage and leakage at the splicing part, and better ensuring the use reliability of the buried sewage treatment device.

[0023] The following will further describe the embodiments of the utility model in detail with reference to the above drawings.

Top reserved platform, 8. Pipe orifice reserved platform, 9. Side reserved platform, 10. Reinforcement area, 11. Blank area.

[0025] A splicing and assembling type underground sewage treatment device, as Figure 1 、 Figure 2 shown, is mainly an underground device for urban sewage treatment and is an important part of the urban sewage treatment pipe network. Its structure is composed of two bent tank bodies 1 and several straight tank bodies 2.

[0026] On the outer surface of each of the described bent tank bodies 1, there are multiple radially surrounding solid ring ribs 4 and multiple solid arc ribs 5 distributed in a concentric circle diffusion shape from the inner side of the bend. Each solid ring rib 4 is cross-connected with each solid arc rib 5 to form an integral body, thereby constituting the reinforcement structure of the entire bent tank body 1, that is, a fan-shaped reinforcement area 10 is arranged on the outer surface of each bent tank body 1, thereby enhancing the structural strength of the bent tank body 1.

[0027] On the outer surface of each of the described straight tank bodies 2, there are multiple radially surrounding solid ring ribs 4 and multiple solid transverse ribs 6 extending along the axial direction. The multiple solid ring ribs 4 are equidistantly distributed along the axial direction, and the multiple solid transverse ribs 6 are circumferentially distributed on the outer surface of the straight tank body 1. Each solid ring rib 4 is cross-connected with each solid transverse rib 6 to form an integral body, thereby constituting the reinforcement structure of the entire straight tank body, that is, a cylindrical reinforcement area 10 is arranged on the outer surface of each straight tank body 2, thereby enhancing the structural strength of the straight tank body 2.

[0028] Meanwhile, at the bending part of each bent tank body 1, there are a top reserved platform 7 and a pipe orifice reserved platform 8. The top reserved platform 7 is mainly cut into the tank opening of the bent tank body 1 according to actual construction needs. In this embodiment, there are two pipe orifice reserved platforms 8, which are respectively located on both sides of the top reserved platform 7. They are cut into the liquid inlet and outlet of the bent tank body 1 according to actual construction needs; in this way, the liquid inlet and outlet can be located at the same end, facilitating the subsequent connection of terminal equipment.

[0029] On each of the described straight tank bodies 2, there are a top reserved platform 7 and a side reserved platform 9 arranged on the side of the top reserved platform. The top reserved platform 7 is mainly cut into the tank opening of the straight tank body 2 according to actual construction needs. The side reserved platform 9 is cut into a connection hole according to actual construction needs for facilitating the external connection of pipes.

[0030] The two bent tanks 1 are respectively arranged at both ends with their bent openings facing each other, and then the two bent tanks 1 can be directly spliced and assembled according to the actual situation of the construction site to form a ring-shaped sewage treatment device connected end to end. Or the two bent tanks 1 can be jointly spliced and assembled through a plurality of straight tanks 2 to also form a ring-shaped sewage treatment device connected end to end.

[0031] In this embodiment, the bent tank 1 is in a semi-circular shape. Therefore, directly splicing and assembling the two bent tanks 1 to connect end to end will form a circular sewage treatment device, and jointly splicing and assembling the two bent tanks 1 through a plurality of straight tanks 2 to connect end to end will form a straight circular sewage treatment device. At this time, the plurality of straight tanks 2 are spliced and assembled in sequence along the axial direction. It can be seen that when the number of selected straight tanks 2 is large, the corresponding axial length is long, that is, the length of the formed straight circular sewage treatment device is longer; when the number of selected straight tanks is small, the corresponding axial length is short, that is, the length of the formed straight circular sewage treatment device is shorter. Therefore, it can be selected according to the different sewage treatment volumes of the sewage treatment device.

[0032] Of course, the sewage treatment device can also form various ring-shaped structures according to the different bending styles of the bent tank 1. For example, if the bent tank is in the shape of " " or "[" or "<" or "〔", etc., various bent shapes, then the corresponding sewage treatment device can form various ring-shaped outer shapes such as an elliptical ring shape or a rectangular ring shape. Therefore, the sewage treatment device only needs to form a ring-shaped structure connected end to end, without restricting the shape, size or style of the ring.

[0033] Obviously, through this splicing and assembling structure, not only is the splicing and assembling method more flexible, but also the formed sewage treatment device forms a ring shape connected end to end. Without the need for additional frames to bind, the overall structure can always maintain stability and is also easier to use.

[0034] The end faces of the two described bent tanks 1 are in contact with each other and are detachably spliced and assembled; the end face of each bent tank 1 is in contact with the end face of the adjacent straight tank 2 and is detachably spliced and assembled; the end faces of every two adjacent straight tanks 2 are in contact with each other and are detachably spliced and assembled.

[0035] In addition, between the end faces of the two curved tanks 1, between the end face of each curved tank 1 and the end face of the adjacent straight tank 2, and between the end faces of every two adjacent straight tanks 2, there are respectively provided concave-convex dovetail structures 3 to form a detachable splicing and assembly. In particular, the concave-convex dovetail structure 3 is a splicing and assembly structure that can be disassembled and assembled in the vertical direction. Therefore, the adoption of this detachable splicing and assembly structure can not only enable the sewage treatment device to adaptively adjust the splicing height between adjacent two tanks according to the height difference of the terrain at the construction site, facilitate normal use under such special buried conditions, but also effectively prevent the backfilled earthwork from crushing the splicing part, thereby eliminating the risk of damage and leakage at the splicing part and better ensuring the use reliability of the buried sewage treatment device.

[0036] A blank area 11 is reserved between the strengthening area 10 on the outer surface of each of the described curved tanks 1 and the concave-convex dovetail structures 3 at both ends, and a blank area 11 is also reserved between the strengthening area 10 on the outer surface of each straight tank 2 and the concave-convex dovetail structures 3 at both ends. The curved tank 1 and the straight tank 2 facilitate the splicing and assembly of the concave-convex dovetail structures 3 between adjacent two end faces through these blank areas 11.

[0037] The above description is only a specific embodiment of the present invention. Those skilled in the art should understand that any structural design equivalent to this embodiment should be included within the protection scope of the present invention.
